Valatation Rule to only allow Uppercase X

Hi,

This should be an easy question for everyone but me.  I want to set a valadation rule to only allow an Uppercase X.  If I set it to just "X", it allows uppercase and lower case.  I tried the expression builder but I had bad syntax... so something was wrong!

Thanks
Jim

Try in the after update event:

Me.txtBox = Ucase(Me.txtBox)

If you just want show uppercase set the Format property of the field to >

Bit of a weird one this :-)

Asc([txtBox])=88

where txtBox is the name of the field you are validating.

=chr(88) will accept upper or lower which does not make sense!

Probably the most user-friendly way though is to use just X in validation and Nestorio's  Me.txtBox = Ucase(Me.txtBox) to put it right if they get the case wrong
